Abstract

LiNi0.5Mn1.5O4 is synthesized by a sol–gel method, and its performance as cathode of high-voltage lithium-ion battery is improved by using poly(vinylidene fluoride-co-hexafluoropropene)-based gel polymer electrolyte (GPE). The results obtained from charge/discharge tests demonstrate that the cyclic stability of LiNi0.5Mn1.5O4 is significantly improved by using the GPE, especially at elevated temperature. After 150 cycles, the discharge capacity of LiNi0.5Mn1.5O4 drops sharply from 127 to 60 mAh g−1 when using liquid electrolyte, while remaining a high value when using GPE, from 134 to 124 mAh g−1. The improved performance is attributed to the enhanced stability of the electrolyte when substituting GPE for liquid electrolyte.
